CUBA’s rivers are running clean, with low levels of fertiliser pollution, thanks to decades of sustainable farming, according to a joint scientific study published in the journal Nature on Tuesday.

Teams from the University of Vermont in the United States and the Cienfuegos Centre for Environmental Studies in Cuba, led by Paul Bierman and Rita Hernandez, sampled water from more than 25 water basins in the centre of the island.

It was the first time in more than 60 years that scientists from Cuba and the US joined forces to study the socialist country’s hydrology.
